That's exactly what I was thinking of for the Beowulf node problem.

I know how to do this by changing the configurations, but not how to specify a one time change that doesn't need to be manually undone later. Is either of these boot loaders capable of doing the logical equivalent of: grub-next-boot-only -default 3 (Override whatever default is in the config file, but just for the next boot.)
